BOILER FEEDER AND INDICATOR.

SPECIFICATION forming part of Letters Patent No. 485,976, dated November8, 1892.` Application filed April 26, 1892. Serial No. 430,702. (Nomodel.)

.To all whom t may concern:

Be it known that l, PRENTICE A. NEWMAN, of Runge, in the county ofKarnes and State of Texas, have invented certain new and usefulImprovements in Automatic Steam-Boiler Feeders and Indicators; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit pertains to make and use it, reference being had to the accompanyingdrawings, which form part of this specification.

My invention relates to an improvementin automatic steam-boiler feedersand indicators; and it consists in the novel features of constructionand in the combination and arrangement of parts which will be fullydescribed hereinafter, and more particularly referred to in the claims.

The object of my invention' is to provide an improved automaticmechanism for controlling the feed-pump and actuating an alarm- Whistle.

Referring to the accompanying drawings, Figure l is a longitudinalsectional View of my improved feeder and indicator. Fig. 2 is across-sectional View of the rotary valve and its casing. Fig. 3 is adetached View of the valve-casing. Fig. 4 is a similar View of thevalve.

A represents a water-column having a chaml berB at its lower end for thereception of `the steam-boiler.

sediment, and C a pipe connection leading to Projecting outward from theupper end of the column A is the hollow arm D. On the outer end of thisarm is the valve-chamber E, which is placed on the pipe which admitssteam to the pump from the boiler. Openings are formed on opposite sidesof this valve chamber, and inserted therein is the circular casing F,which is provided with a series of parallel slots on its under side anda wide slot G to one side of and above the first-named slots, as shown.At the top of the casing is also formed the slot I. Placed in thiscasing is the circular-valve J, and connected thereto is the rod K. Thisrod projects through the slot G and extends inward through the arm D tothe chamber A, and pivotally secured to this inner end is the float L,which is formed of copper or other suitable material and which dependsin the Steam being admitted to the pump through the pipe on which thevalve-chamber E is placed, the same will be operated and Water forced orinjected into the boiler, raising the level therein and alsoin thecolumn A. The iioat L is carried upward by th is means, and by means ofthe rod K the rotary valve is turned. The latter is slotted tocorrespond with the slots G and I of the valve-casing, so that when thefloat is down, the water being low, steam Y is allowed to pass to thepump; but the upward movement of the float turns the valve and placesits solid portions over the said slots in the casing, closing them andshutting otf the supply of steam to the pump. Thus it will be seen thatthe operation of the pump is automatic, being controlled by the level ofthe water inthe boiler, which it-feeds.

The valve-chamber E is provided with the side openings M M, which are inline and formed as a section of a cone, so that the latter opening ismuch smaller than the former, and the casing F, which tits therein,heilig conical in form, it will be seen thatit tits the said openingsquite tightly,being placed in position through thelargeropeningM. Acrossthe rear end of this casing is the barN,tl1rough which projects theset-screw N', and across the front of the opening M is the bar O, havingthe inwardly-extending set-screw O', and between these screws is thevalve J, which is also conical in form, and by means of the said screwsthe valve may be adjusted longitudinally and all wear thus taken up. Theopenings M M are closed by the screw-plugs P. By means of the conicalform of casing and valve a very tight-fitting connection is formed.Extending around and above the outer side of the valve-casing is thepassage P', which at its upper end communicates with the steampipeleading to the pump, being controlled by the valve Q. When it is desiredto admit water to the boiler by starting the pump inlOO dependently ofthe automatic float attachment, the said valve is opened, when steamwill be passed around the circular valve, and the pump thus operated.The innerY wall of this passage Pforms arest for one side of the casingF.

If from any cause the pump should not start when the valve J is opened,the receding water in the column A, carrying the float with it, willcause the latter to operate an alarm, which will attract the attentionof the engineer. This alarm consists of a whistle R, which is mounted onthe top of the arm D, being supported on the removable plate S, asshown. Y Secured tothe under side Vof this plate is the spring-arm T,which is fastened to one side of the whistleopening, and directlybeneath the 'said opening upon the said arm is the clapper U, whichnormally closes the said opening and prevents the escape of steam to thewhistle. Depending from the free end of this spring-arm is the loop V,th rough which extends the valve-operating rod K. Vhen the water dropsbeneath the requredlevel in the column to operate the valve, the saidloop is drawn downward by the continued downward movement of the rod K.The clapper removed from the whistle-opening and steam being thusadmitted therein an alarm is sounded, warning the engineerof the stateof the water-level in the boiler.

The column A is provided with a steam connection A at its upper end foradmitting steam thereto. The column is provided with a steam-pressureand a water-gage similar to those provided for the boiler.

A blow-ohc valve is placed at the lower end Yof the sediment-'chamber B,so thatV the exactY condition of the water and steam can be ascertainedat any time.

Having thus described my invention, I claiml. The combination of awater-column, a hollow arm projecting therefrom, a valvechamber at theouterend of the arm, a valve therein, a fioat in the column, and aconnection between the valve and float, the said valvechamber beingformed with a passage around said valve, substantially as shown anddescribed.

2. The combination, with a Water-column, a hollow arm projectingtherefrom, a valvechamber at the outer end of the arm, and a rotaryvalve .in said chamber, the chamber being provided with an independentsteampassage around the valve, of a wall which separates the saidpassage from the main valve-passage, a casing which rests against thesaid wall and in which the valve rotates, a iioat in the water-column,and a connection between the said float and rotary valve, substantiallyas shown and described.

3. The combination, with a water-column, a hollow arm projectingtherefrom, and a valve-chamber onthe outer end of said arm, which isprovided with a transverse opening, which extends through the same, of aslotted valve-casing adapted to fit the said opening, a slotted valve insaid casing, cross-bars at the ends of the casing, set-screws extendingthrough said bars, which engage the valve, a float in the column, and aconnection between the float and valve, substantially as shown anddescribed. Y

4. The combination, with a water-column, a hollow arm projectingtherefrom, and a Valve-chamber at the outer end of the arm, which isprovided with a transverse opening extending through it, of a slottedcasing adapted to tit theV said opening, a rotary slotted valve in thecasing, a bar made integral with one of the casing ends, a set-screw insaid bar, which engages the valve, a bar at the opposite end of thecasing, which issecured to the valve-chamber,asetscrew therein, whichengages the opposite end of the valve, plugs for the openings in thesaid valve-chamber, a float in the column, and a connection between thesaid rotary valve and iioat, substantially as shown and described.

5. The combination, with a water-column, a hollow arm projectingthereform, a valvechamber at the outer end of the arm, and a valvetherein, of a float in the column, a rod connecting the valve and fioat,a whistle on the said hollow arm, a spring-arm carrying a clapper whichcloses the said whistle, and a loop depending from the spring-arm,through which passes the rod which connects the Valve and Iioat,substantially as shown and described.a

b'. The combination, with a water-column, a hollow arm projectingthereform, a valvechamber at the outer end of the arm, and a valve insaid chamber, of a oat in the column and a rod which connects the saidvalve and ioat., a plate in the upper surface of the said hollow arm, awhistle supported thereon, a spring-arm secured at its end to theunderside of the plate, a clapper on said arm, and a loop depending from thefree end of the spring-arm, through which the said rod extends,substantially as shown and described.
